I need to edit the category panel on the "Edit post" page. The one that is in the right side just below the "Publish" button.
Which file(s) do I need to look for to edit it?
What I need to do is find a way to make WordPress display the categories in the same order as they are before I select any of them.
Once I select some categories and publish the post, if I come back to it, the categories will be displayed without the parent-child indentation and out of order. I'm trying to avoid this, it makes it very difficult to select new categories.
How can I do it?
Thanks in advance!
